PRESS FOR PLOW-SCRAPERS.

Application filed. June 5, 1917.

To all whom it may concern:

Be it known that I, ROBERT P. lViLLIAMs, a citizen of the United States,residing at Winder, in the county of Barrow and State of Georgia, haveinvented new and useful Improvements in Presses for Plow-Scrapers, ofwhich the following is a specification.

The present invention relates generally to presses, and moreparticularly to that type adapted for bending farm implements, such asscrapers, cutters or the like.

The primary object of the present invention contemplates the productionof a press of the above stated character which is simple inconstruction, durable and efficient in use and may be manipulated in asimple and expeditious manner to facilitate the bending of the farmimplement, and wherein the table is provided with a stud, which, uponthe placing of the implement upon the table, will extend through anopening formed in such implement for the purpose of accurately retainingthe implement on such table.

With the above and other objects in view, the invention consists in thenovel features, details of construction and combination of arts whichwill hereinafter be more fully set forth, illustrated in theaccompanying drawing and pointed out in the appended claim.

Figure 1 is a perspective View of the press in a partial open positionwith a scraper positioned thereon;

Fig. 2 is a transverse sectional view; and

Fig. 3 is a plan view of the press shown in open position.

Referring more particularly to the accompanying drawing, in'which likecharacters of reference refer to corresponding parts in the severalviews, the character 5 denotes the press generally, which may beconstructed of any material found desirable, and primarily employed forthe bending or pressing of scrapers, cutters or the like such as arecommonly used on plows and similar agricultural implements.

To this end, the press 5 embodies a base plate 6 provided along thefront edge thereof with a flattened attaching flange 7 provided withspaced openings 8 through which suit- Specification of Letters Patent.

table 10 tapering downwardly in a direction toward the attaching flange7 for a purpose to be hereinafter more fully set forth. The table isprovided with a pair of smooth faces 11 merging in a direction towardthe centrally located inclined block. 12. The block 12 is positioned atright angles with respect to the faces 11 of the table, and the sidewalls of the blockincline downwardly and outwardly in a direction towardthe faces 11 of the table, consequently, after the squared stud 13 isprojected through the opening 141, of the scraper A, and pressure isbrought to bear upon the material forming the scraper while in a heatedcondition, the block 12 will provide the scraper with a substantiallyU-shaped clip 15 for connection of the scraper to the agriculturalimplement in a practical manner. Centrally located on the flange 7 intransverse alinement with the block 12 is an apertured bearing 16through which the pin 17 projects, and likewise through the spaced cars18 of the top or movable member 19, serving to pivotally connect themovable member to the base plate for a vertical swinging movement.

The top or movable member 19 comprises a shoe 20 having a convexed outerface 21, straight opposite end walls 22 and the inner face 23 of theshoe tapers from the opposite end walls in a direction toward the centerto conform to the inclination or angle of the smooth faces 11 of thetable. In order to permit a snug engagement of the confronting faces ofthe table and shoe upon the latter assuming a closed position, I providein the inner face 23 a depression 24-, and the bottom wall forming thedepression is centrally formed with a squared opening 25, the block 12fitting in the depression 24, while the pin 17 projects into the squaredopening 26 upon the bending action of the scraper or cutter. At thispoint, I desire to have it understood that this press may be soconstructed to facilitate the simultaneous bending of two or morescrapers or cutters, if desired.

The block 12 is provided with a concaved end 26 with which the conveXedlip of the shoe, designated by the character 27, snugly engages forguiding the downward movement of the shoe to accurately position theshoe upon the material being bent, in order that each of the wings B ofthe scraper A may be given a perfect bend. A socket 28 is provided onthe convexed outer face of the shoe along the transverse center thereofin which is inserted a hand lever 29 for operating the shoe to open andclosed position. The side walls forming the socket 28 are separated attheir outer ends, providing the spaced ears 18 of the shoe. To assureagainst any accidental movement or displacement of the scraper from thetable, during the bending or pressing thereof use is made of a pairofspaced converging projections 30 formed on the outer edge of the tableat points to opposite sides of the block 12.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of construction and the method ofoperation will be readily apparent to those skilled in the'art to whichthe invention relates, and while I have described the principles ofoperation of the invention, together. with the device which I nowconsider to be the best embodiment thereof, I desire to have itunderstood that ranged table formed contiguous therewith,

a block on said table and centrally provided with a projection, amovable member connected with the base plate for vertical swingingmovement and formed on the under face and centrally thereof with adepression having an opening through which the said projection passes, aconvexed lip formed on one edge of the movable member and adapted toengage with one edge of the block upon the closing of the movable memberto clamping position, substantially as and for the purpose specified.

In testimony whereof Iaflix my signature.
